Question no 3589 : Roll forward in MRP Run

In SAP PP as at ECC6.0 EhP6, A user wants a rolling forward for a material with MRP type with firming type = 1, to be set up for a production material master. Rolling planning time fence means new planned orders which are firmed within a planning time fence, when an unforeseen production failure occurs, it can happen that such firmed planned orders are not being processed because time passes. What solution would you recommend to automatically delete these kinds of firmed planned orders?

(only one answer)

A)  Roll forward period assign to the MRP Group.
B)  Roll forward period assign to the MRP Type.
C)  Roll forward period assign to the MRP Controller.
D)  Roll forward period assign to the Material Type.
E)  Roll forward period assign tot he Order Type.
.

Answer: A

Firmed planned orders are subject to normal firming logic; that means, the system does not delete them automatically during the planning run when they are no longer needed. You can, however, define a roll forward period. The system then deletes all firmed planned orders that lie before the roll forward period automatically. The master plan is thus updated.
The basic setup is the Roll forward period to be assigned to the MRP Group where it is then assign to the Material Master in the MRP 1 view.
